WOW never thought id get a email from 4wheel parts.. lol I run 38s now in Gumbo size bias.. I was thinking about going radials with the I rocks in the 39.5 15" rim or should i go with bias?? I run them year round. mainly mt use..

The 39.5's are available in both radial and bias, in limited quantities. I run the bias and love them. They actually handle better on the street than my 35" MTR's did. The wear is not the best but I guess that is the sacrifice for a tire that works so well off road. I have ran just about every Swamper there is and the Irok has been the best performing one yet. FWIW.
